18650 battery 3.7v 1800mah

　　Characteristics of 18650 battery 3.7v 1800mah

　　1. Longer life span.

　　Lead-acid batteries have a cycle life of up to about 300 times, and a maximum of 500 times, while lithium iron phosphate batteries have a cycle life of more than 2,000 times, and standard charging (5 hours) can reach 2,000 times. Lead-acid batteries of the same quality need to be used for half a year, and maintenance and repairs need to take half a year. The most is only one year. Under the same standards, the service life of lithium iron phosphate rechargeable batteries Up to 7-8 years. Overall, the performance price comparison will be 4 times higher than that of lead-acid batteries.

　　2. Application security.

　　It completely solves the safety risk problems of lithium cobalt oxide batteries and lithium manganate batteries. Lithium cobalt oxide batteries and lithium manganate batteries will explode when there is an obvious impact, posing a threat to the personal safety of consumers, while lithium iron phosphate Batteries are less likely to explode even in the most extreme car accidents.

　　High-current 2C rapid battery charging. Under a special charging head, the battery can be fully charged in 40 minutes, and the starting current reaches 2C. Lead-acid batteries currently do not have this feature.

　　3. It is heat resistant.

　　The maximum electric heating temperature of lithium iron phosphate reaches 350°C to 500°C, while that of lithium manganate batteries and lithium cobalt oxide batteries is only 200°C. The operating temperature range is very wide (-20C--+75C). The maximum electric heating value of heat-resistant lithium iron phosphate batteries reaches 350℃500℃, while lithium manganate batteries and lithium cobalt oxide batteries are only 200℃.

　　4. Capacity.

　　The capacity is larger than ordinary rechargeable batteries (lead-acid batteries, etc.). When a rechargeable battery is often in a charging state, its capacity will quickly decrease below the short-circuit capacity. This situation is called memory. For example, nickel metal hydride and nickel cadmium batteries have memory capacity, but lithium iron phosphate batteries do not. The battery can be charged at any time no matter what the situation is, without having to put it first and then charge it.

　　The volume of a 18650 battery 3.7v 1800mah with the same volume is 2/3 of the net weight of a lead-acid battery and 1/3 of the net weight of a lead-acid battery. This battery does not contain excessive heavy metals or non-ferrous metals (Ni-MH batteries require non-ferrous metals), is non-toxic (verified by SGS), has zero pollution, complies with European RoHS standards, and is an absolutely green and environmentally friendly battery.

　　5. There is no memory hazard.

　　The cathode material of the positive battery determines the characteristics of lithium-powered lithium batteries. Lithium iron phosphate batteries as the raw material of lithium batteries have only appeared in recent years. In October 2005, China developed a large-space 18650 battery 3.7v 1800mah. Compared with other materials, its safety factor and cycle life are incomparable, which are also important performance indicators of power lithium batteries. The battery charging cycle time reaches 2000 times. The working pressure of a single battery charge is 30V. It will not ignite and will not explode during puncture. Large-space lithium batteries made of 18650 battery 3.7v 1800mah cathode materials are easy to use in series. In order to meet the needs of battery charging and discharging, battery vehicles often need to be charged. Because of its non-toxicity and zero pollution, high safety factor, widely sourced raw materials, high quality and low price, and long service life, it is an ideal battery cathode material for the new generation of lithium batteries.
